Vertical Antenna Installation
It's springtime, the grass is rising and the birds are chirping ... and the antenna plans you had simmering all winter long are now ready to be served!
Here's a session devoted to a careful and thoughtful installation of a 7-band Butternut antenna at the home of our dear friend in West Virginia: Nancy NJ8B ... Hope this gives you some good ideas for your own antenna-raising party; and perhaps you can toss in some of your own wisdom during our Teamspeak session!
73,
~George N2APB and Joe N2CX
